Abstract

The paper focuses on the green shipping methodologies and environment friendly practices. Liquefied natural gas (LNG) is one of the most effective alternatives to traditional shipping fuels. Ports have LNG re-gasification systems, which generally use Open Rack Vaporizers (ORVs) to convert the LNG to NG. In this process, a lot of the ‘cold energy’ is lost. A proposal for a LNG re-gasification system has been made in this paper which can be installed both on-board a ship or in a port and will successfully utilize the cold energy of LNG. In addition, analysis of the experimentation of inert hydrogen gas used in cooling exhaust gas recirculation (EGR) systems on-board ships to stop the production of NOx at peak temperatures in the engine chamber has been done. The uses of various catalysts on selective catalytic reduction (SCR) systems to curb NOx production and data analysis on NOx reduction after treatment have been studied. Germane and pertinent observations were taken for the following procedures.

Keywords: High efficiency, energy extraction, selective catalytic reduction (SCR), exhaust gas recirculation (EGR), liquefied natural gas (LNG)
